Chord Leyline speaker cable came into being during the first wave of home A/V set-ups. Amplifiers for all rooms were often fitted in one place. This meant long (and sometimes very long) runs of speaker cable throughout the structure. It also meant that the cable had to be discrete and affordable. There were already a lot of cheap cables available, so we needed to develop something better. Size restrictions meant using 16AWG conductors. Long runs meant using a twisted pair design – which suited us as we already using twisted pair geometry to produce speaker cables anyway. Cost ruled out silver-plating or using PTFE, so after much thought we settled on oxygen free copper conductors and low-density polyethylene insulation for conductors.
The problem came with longer runs and a loss of high frequency detail along with space and coherence. We solved this by tin-plating the conductors. It wasn’t an overly bright cable and would now carry high frequency detail over longer runs. The final version of Leyline featured tin-plated oxygen free copper conductors, low density HDPE insulation, a twisted pair conductor configuration and a protective LS0H outer jacket (low smoke, zero halogen), meaning Leyline can be used in public buildings.
Leyline is also a great choice for rear speakers in bigger systems. It can be used with pretty much whatever level of speaker cable you choose for the front speakers, with no loss of overall balance.
